Rockwell Automation has recently added an M frame size model with current ratings of 300-800A to its popular Bulletin 140UE family of competitively priced, high-quality, CE-marked MCCBs (moulded case circuit breakers).

Flexible and versatile, the 140UE MCCBs complement the many other components available in the Allen-Bradley Modular Control System (MCS) Plus range. Sharing identical dimensions with the Allen-Bradley 140U range of UL498-listed MCCBs means that both ranges are fully interchangeable for machines and panels destined for European or North American markets.

Bulletin 140UE MCCBs are available in frame sizes H, J, L, M and N, with current ratings from 16-160A, 20-250A, 200-630A, 300-800A and 600-1250A, respectively. A compact, space-saving design means that Bulletin 140UE MCCBs offer a footprint that is claimed to be up to 40 per cent smaller than comparable current-rated products from other manufacturers. Both thermal-magnetic and electronic trip types are available in three- and four-pole versions, in frame sizes J, L and M. H frame sizes are available in thermal-magnetic, and N frame in electronic trip versions. All the devices in the Bulletin 140UE range meet the requirements of IEC 60947-2, are CE marked and are KEMA-KEUR third-party tested and certified.

A comprehensive range of internal accessories is also available for the 140UE line, including trip alarms, auxiliary contacts, under-voltage release and shunt trips. All internal accessories are field-installable without compromising certification or approvals. A full range of external accessories is also offered, such as plug-in adapters, terminal lugs/covers and motor operators. All Bulletin 140UE MCCBs have the option of a rotary-operating mechanism with an IP66-rated interlocking door handle or flexible, cable operating mechanisms.
